I called, stated the problem and they scheduled an appointment. He was at my house within the hour. He figured out the issue and explained the solution in lay terms. I was very pleased with the experience. They are my go-to company for all things plumbing, heating and HVAC!

Excellent Customer Service and Great Communication




We called in for emergency service after arriving home with one furnace not operating. We spoke twice to a BD rep who answered the emergency line. He was friendly and understanding when I said we were trying a few things, but would they put us on the list to come out that night. He explained the charges to us on the phone which was important to us. Later a women from BD called us to see if we were home and available so that they would send a technician out who was traveling from Algonquin. Our Technician, Tim Mays was thorough explaining that the furnace had a problem seen on other furnaces of the same model, water was blocking the pressure switch tube . While the latter was drilled out, we may face the problem again and we may need to replace the control board.


Efficient service




The Black Diamond team was here at the scheduled time, considerate of my just-cleaned carpets, and finished the work quickly. Thanks for your help, guys!


Prompt, fast service




The Black Diamond team was here this morning promptly at 8, and performed the required repair to a bathroom outlet quickly. Thanks for your help!


Great service and very quick to respond




Very happy with the response time for this emergency and the pleasant nature of Josh and his work habits. He took care of things in a very professional manner.


Service Technician responded very quickly - fair price too





Almost Needlessly Gouged, No Apology




My most recent encounter with Black Diamond had me wondering if I was really dealing with the same company I knew and trusted in the past. I'm a long-time customer who for the most part has been very satisfied in prior dealings (obviously, or I wouldn't have been a long-time customer). This time on a stopped up sewer call, I was talked out of any kind of procedure that might have cleared the obstruction with minimal side effects, in favor of lining up an appointment to cut a hole in my basement floor to find and deal with the stoppage. Fortunately I ran across a clean out opening under a nearby rug the Black Diamond employee never considered looking under, and before jack hammering began at the follow-up appointment had it opened and the offending rag causing the obstruction removed. I then had to insist that the additional camera charge from the second visit be removed, because it never should have been necessary had the employee done a thorough job in solving the problem to begin with. I don't know that I will ever use Black Diamond again, unless I have reason to believe it returns to being the company I remember from prior encounters.


Tankless Hot water heater




Excellent


Felt Like a Scam





Outstanding Service!




Nick G. recently installed a new furnace for me. He took the time to make sure I was purchasing the one I needed, giving me all the other options. The entire process was explained in terms I could understand. After the install everything was cleaned up (better than before). Nick took the time to make sure I understood how to operate, and care for it. Thanks Nick!


Courteous electrical service




Always good to do business with Black Diamond.


Excellent service, True Professional




Gerad did a great job and was very easy to work with. He is professional and knowledgable. I will definitely ask for him in the future.
